Like Xu a827c007c7 perf config: Refine error message to eliminate confusion ... If there is no configuration file at first, the user can write any pair of "key.subkey=value" to the newly created configuration file, while value validation against a valid configurable key is *deferred* until the next execution or the implied execution of "perf config ... ". For example: $ rm ~/.perfconfig $ perf config call-graph.dump-size=65529 $ cat ~/.perfconfig # this file is auto-generated. [call-graph] dump-size = 65529 $ perf config call-graph.dump-size=2048 callchain: Incorrect stack dump size (max 65528): 65529 Error: wrong config key-value pair call-graph.dump-size=65529 The user might expect that the second value 2048 is valid and can be updated to the configuration file, but the error message is very confusing because the first value 65529 is not reported as an error during the last configuration. It is recommended not to change the current behavior of delayed validation (as more effort is needed), but to refine the original error message to *clearly indicate* that the cause of the error is the configuration file.
